I am currently working with button_tag to create a remote styled answer submission quiz. When pressing this button, instead of posting the new record, it is throwing an error.

ActiveRecord::RecordNotFound (Couldn't find Answer without an ID):

When looking at the server logs I see it is trying to work with these params when trying to post Parameters: {"{"answer_id":59}"=>nil, "id"=>"15"}

What I am looking, or expecting to see is this.
Parameters: {"answer_id"=>"59", "id"=>"15"}

Here is the button_tag I am using.

<% @question.answers.each do |answer| %>

  <%= button_tag "#{answer.answer.titleize}", class: 'btn btn-block btn-lg btn-primary', data: {

    remote: true,

    method: :post,

    url:    answer_question_path(@question),

    params: { answer_id: answer.id }

  } %>

<% end %>

Here is my response controller which is responsible for submitting the POST request.

class ResponsesController < ApplicationController

    def answer

        question = Question.find(params[:id])

        answer   = question.answers.find(params[:answer_id])

        response = question.responses.find_or_initialize_by(user: current_user)



        if response.update(answer: answer)

            head :ok

        else

            puts 'Something went wrong chief' 

        end

    end



    private



    def responses_params

        params.require(:response).permit(:user_id, :question_id, :answer_id)

    end

end

I have tried using to_json on the parameter with no success and have not been able to find any solution elsewhere on SO or other forums. Any ideas?

This seems to be an issue with button_tag in the feature I am using it for.

button_tag creates a button element that defines a submit button, resetbutton or a generic button which can be used in JavaScript. button_tag is also an action view helper but is defined as a FormTagHelper.

button_to generates a form containing a single button that submits to the URL created by the set of options. button_to is a UrlHelper while button_tag is a ViewHelper.

Below is the button_tag code I was using which was creating the issue described above. Using button_tag fixed my parameters issue and also looks a bit cleaner. I hope this helps anybody else having issues with button_tag in the future.

<%= button_tag "#{answer.answer.titleize}", class: 'btn btn-block btn-lg btn-primary', data: {

    remote: true,

    method: :post,

    url:    answer_question_path(@question),

    params: { answer_id: answer.id }

  } %>





<%= button_to "#{answer.answer.titleize}", 

      answer_question_path(@question), 

      class: 'btn btn-block btn-lg btn-primary',

      params: { answer_id: answer.id },

      remote: true %>
